Description
Summary:We are developing two prototype systems based on high-T sub(c) superconductor (HTS) samplers for measuring high-frequency electrical waveforms. One is a digital waveform measurement system in which high-frequency digital signals are directly inserted into the sampler circuit via a 40-GHz frequency assembly. The system can reconstitute a 5.9-Gbps digital waveform at 37 K. The other system is a current-waveform measurement system in which the signal current is picked up by a superconducting closed loop, and the waveform is measured by the sampler included in the loop. A sinusoidal waveform at 7 GHz was successfully measured using this system at 38 K. copyright 2001 Elsevier Science B.V. All rights reserved.
